Stetson-Ross Model 4A 16??? X 20??? Timber Sizer. Round 4-knife cutterheads are mounted in babbitt bearings (ball bearing conversion available). Includes counter shaft assembly, remote tower for setting top and side cutterhead position, jointers, and heavy steel sub-base with pick-eyes at each end. Sizer shows virtually no wear and has obviously been used very little over the years. It is the best timber sizer we have seen in terms of condition. See photos of Stetson-Ross Model 4A 16??? X 20???
